I found a couple old threads on this topic, from back in April and May. I hadn't seen it before until this week. I charge my phone fully in the evening, and in the morning it's critically low. PVMtpServiceStart is the service responsible for 90% of that drain. Right now my battery is going down fast after being plugged in all night, and that service is 71% of the use. I can't stop it or figure out what's using it. I've stopped Blockbuster and DRM and a few others, but nothing helped. I was able to stop pvmtpservicestart yesterday, but today it's not showing up other than on battery usage. All I can think of that's different is that I connected my phone to transfer some pics to my computer, but I've done that plenty of times before without causing <8hr standby on my battery. Does anyone know what this service is, and more importantly how to stop/remove it? Other than rooting, which I don't want to do right now. Help! Thanks!
